With default ubuntu's 8.04 2.6.24 kernel the problem can not be
repeated
This could very well be due to one/several of the as-yet un-addressed
chipset errata for the 6081. Someday we'll have software workarounds
for those, but I'm (still) waiting on Marvell for stuff.
I was going through logs for the last night and noticed something:
Currently I have only 7 disks connected to 6081 controller, port 5 is
free, and now stalls have been happening only on ports 0, 2 and 3. So it
seems something on high port is affecting corresponding lower port too.
Harri / Artem: what type/speed of slots are your 6081 controllers in?
PCI, or PCI-X? Bus speed?
As mentioned earlier, 33MHz, 66MHz and 133MHz. Motherboards are: some
Asus board with VIA chipset, Supermicro P4SCI and Supermicro X7SBE. I
think P4SCI has 66MHz 64bit PCI, not PCI-X.
